Figure 8 - Application Circuit: MEI Compatible Type 2 Telephone
Unless stated otherwise, resistors are 1%, 0.1Watt; capacitors are 5%, 6.3V.
For 1000Vrms, 60Hz isolation from Tip to Earth and Ring to Earth:
R1,R2
430K, 0.5W, 5%, 475V minimum
(e.g. IRC type GS-3)
C1,C2
2n2, 1332V minimum
If the 1000Vrms is handled by other methods then this circuit has to meet the FCC Part 68 Type B Ringer requirements:
R1,R2
432K, 0.1W, 1%, 56V minimum
C1,C2
2n2, 212V minimum
Common to both sets of R1,R2 and C1,C2:
R3,R4
34K
R8, R9
464K
R13
100K, 20%. Required only if both FSK interface mode 0 and power down features are used.

In a telephone adjunct box application where there is no hybrid or speech IC, if the GS2 gain with respect to Tip/Ring is to be set
to the same as GS1, the GS2 op-amp can be connected as a voltage follower to the GS1 output as shown in Figure 5.
